2 Claims.

The subject of the invention is a scafiold bracket to be used in combination with a ladder.

The main object of the present invention is to provide a bracket, which may be fixed on a ladder at any height and on either side of it, and which bracket is adapted to be used as a carrier for a scaffold platform, or as a carrier for hooks, with which to hang up the ladder or for other similar purposes. It is further the object of the invention, to provide such bracket construction, which will permit the laying of planking or the like between two ladders provided with this new device.

The above and other objects will become apparent from the following description and from the drawing which shows the new device. In the drawing Figures 1 and 2 are a front elevational view and a side elevational view respectively of a ladder with the new scaffold brackets fixed thereon;

Figures 3 and 4 are a front elevational view and a side elevational view respectively of one of the brackets.

Referring now in detail to the drawing there are shown the uprights l and H of a ladder joined by the typical rungs l2 as usual. The brackets are used in pairs and are arranged on right and left hand sides of the uprights, being passed partly always over two consecutive rungs. Each bracket comprises a plate 13 which is consistent with a particular construction of L-shape, the web M of which extends at right angles to the plate. Each web continues into a rectangular flap or ear I5, extending parallel to the plates l3, so that the three members [3, l4 and I5 form a U-shaped member, into which the uprights l0 and I! of the ladder are fitted. The plate I3 is provided with two U-shaped recesses l6 and I1, into which a pair of consecutive rungs 12 of the ladder are fitted. The plate l3 also has, extending between the said two recesses, a tongue l8, in which a plurality of arouately arranged openings i9 are provided. These openings receive a bolt 20, which attaches to the bracket a scaffold arm 2|, which arm is pivoted on a bolt 22, carried by the bracket. The two end portions of the plate [3 above and below the flap or ear 15 project likewise beyond the edge of the ladder uprights Ill and I l, and to these end portions, being provided with holes 23, is bolted a locking bar 24, which bar lies fiat on the ladder upright, for retaining the bracket in secured position upon the ladder upright.

The rungs fit into the recesses l6, and the particular construction of the recesses prevents the rungs from being displaced or shifted.

The brackets are made in such form as to be reversible, and a pair of brackets are required for supporting a scafiold platform, such as indicated by the numeral 26. Furthermore the scaffold brackets can be applied and fixed to the ladder from either side of the ladder uprights, as is shown in the upper and in the lower parts of the Figures 1 and 2. The uppermost brackets attached to the uprights It and Il may be provided with extensible hook members 25, so that the ladder may be used as a suspended utensil.

It is to be noted that certain changes may be made in the form and construction and arrangement of the different parts, without departing from the spirit and the scope of the invention, as characterized by the following claims.

I claim:

1. A device of the class described comprising a U-shaped bracket for association with a ladder having ordinary uprights and rungs, one leg of the U-shaped bracket consisting of a plate having a pair of recesses vertically spaced a distance apart to correspond to the distance between rungs of the ladder, a tongue which separates said recesses, a series of arouately arranged holes in said tongue, a locking bar bolted to the plate for retaining the bracket on the ladder, and the other leg of the U-shaped bracket consisting of a second plate-narrower than the first plate, said second plate having a clamping bolt threaded thereinfor engagement with an upright of the ladder.

2. A device of the class described comprising a U-shaped bracket for association with a ladder having ordinary uprights and rungs, one leg of the U-shaped bracket consisting of a plate having a pair of recesses vertically spaced a distance apart to correspond to the distance between rungs of the ladder, a tongue which separates said recesses, a series of arouately arranged holes in said tongue, a scaffold arm pivoted to said plate and having means for engagement with any one of the holes for retaining the scaffold arm in a selected position with respect to the ladder, a locking bar bolted to the plate for retaining the bracket 0n the ladder, and the other leg of the U-shaped bracket consisting of a second plate narrower than the first plate, said second plate having a clamping bolt threaded therein for engagement with an upright of the ladder.
